You're still required to have an image for K8 and Fam10 each, simply
because we don't support runtime selection of northbridge code in the

The only thing I worked on was getting through CAR on either CPU, then
jumped into the "right" image right afterwards (as was usual in pre-CBFS

So we can debate if we want to keep the current support, but that
requires more work (architecture changes in coreboot) to support
multiple northbridges in all places, not just CAR.
